I have a ?. How do you install the wastegate line,with the info I found they say to hook up to the line on the intercooler pipe. There is no nipple on the hybrid intercooler to run a line.
On the BOV I ran the line to the nipple next to the fuel line on the intake, I could not find any pictures that had the lines or instructions to run the lines.
Thanks in Advance for any help:bow:

I do remeber someone the other day saying the bov needs to be recirc. before the mafs,but get someone with turbo to make sure

For your wastegate you can use one of these:http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATP-FTG-010&Category_Code=FTG
The closer to the turbo you tap the better.

For your BOV, you need a post-throttle body vacuum source. Just about any line you find on the intake manifold will work. Idle the engine and yank a hose of and feel for vacuum if you are not sure about which one to tap into.

Neverlift: You have the right idea, sort of. If your maf is before the turbo like the factory has it set up, then your car will run better with a recirculated BOV.
In order to have the BOV before the maf, you are running a blow-through maf setup. That is when the maf is on the coldpipe. This setup will allow you to run your BOV vented to atmosphere with out any ill-running side effects.

Read Heavy Throttle's FAQ. It shows you which line to tap for the BOV.

As for the wastegate, you need to tap the IC line somewhere. The stock sidemount taps it off the cold pipe. There are various debates so pick about before or after the intercooler. So take your pick and weld on a nipple.

Thanks Guys:naughtyd: I am going to order the nipple that speed monkey listed. I did not want to weld,I can hook that up on the 90* elbow hose.
I can always count on this site for good info:bowdown: I sould have the little items finished in a week.
Hope you all can help me with my next problem setting the SafcII:confused:

Regardless of what the vendor says, my personal opinion is that the clip-on probe for the nipple isn't going to be as good as the weld-on nipple since silicone is very pliable, but you do what works for you.

I have one of those on my car and it works perfectly. It doesn't matter that the silicone is pliable, its an issue of sealing properly. So long as you install it correctly its just as good.

Understood, and I choose to weld. If it works for you then more power to you.

i was told by someone on this fourum to put the wg line after the tb, it helps with spool while shifting or somethin

Consider the source. You can put it behind the throtte plate, but compressor pressure won't be as accurate if you put it before the throttle plate. It may help spool because the throttle plate is closed and compressor pressure is not being diverted to the wastegate, but there may be other consequences you need to consider.
